Abstract

The invention provides a radio frequency system, wireless communication equipment and a protection method of a power amplifier. The radio frequency system comprises a radio frequency path used for transmitting a radio frequency signal in a first frequency band; the power amplifier is positioned on the radio frequency path and is used for performing power amplification processing on the radio frequency signal; and the control module is used for controlling the input power of the power amplifier, so that the input power of the power amplifier is smaller than the maximum allowable input power of the power amplifier. In the embodiment of the invention, the input power of the power amplifier is controlled to be lower than the maximum allowable input power of the power amplifier, the PA is protected from being burnt, and the reliability of the PA is improved to a certain extent.

Description

technical field [0001] The embodiments of the present application relate to the technical field of wireless communication, and more particularly, to a protection method for a radio frequency system, a wireless communication device, and a power amplifier. Background technique [0002] With the wide application of communication technology, the application of wireless communication devices is becoming more and more extensive. In wireless communication equipment, wireless communication is generally realized through radio frequency circuits. A power amplifier (PA) is an important component in a radio frequency circuit, and the radio frequency circuit usually amplifies the power of a radio frequency signal through a power amplifier. However, the power amplifier is prone to burn out during use, resulting in reliability problems. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a protection method for a radio frequency system, a wireless communica...
